Nov 18, 2020 Report
We recently had our home appraised and although I don't know how all of that works I just wanted to say we had Lucas do the appraisal and he was a true pleasure to do business with. He was incredibly kind, professional and really seemed to be a good guy. It's always nice seeing that in a business and we really appreciated the sincere kindness from him. Again, I don't really know how appraisals work but feel it was accurate and fair. Highly recommend this company and Lucas. Thanks so much!
